活躍的ａｓ [作者] 郭廷灶 [內(nèi)容] １９９４年高考英語試題單項(xiàng)填空第３７小題Mother was worried becauselittle Alice was ill,espec ially--Father was away in France. A.as B.that c.during D.if 正確答案為A. as 。本題涉及到as作連詞的用法。 as在英語中是最活躍的詞之一，它既可作副詞、連詞、介詞，也可作關(guān)系 代詞。下面就as引導(dǎo)的各類從句 和慣用法，試作歸納，供同學(xué)們學(xué)習(xí)時(shí)參考。 一、表示比較，意即"象……一樣"。 1. Harry is unusally tall,as are his brothers. 哈利也象他的弟兄們一樣，身材奇高。 2.Army and people are as inseparable as fish and water. 軍民關(guān)系，親如魚水。 3.The work is not so easy as you imagine. 這工作不象你想象的那么容易。 二、表示方式、程度、情況。意即“按照、如同、象”。例如： 1.The number of deer ,mountain lions,and wild roses does not changemuch if people leave thi ngs as they are. 如果人們聽其自然發(fā)展，鹿、美洲獅和野玫瑰的數(shù)量不會(huì)有很大的變化。 2.He writes about china as he sees it. 他照他親眼看見的樣子描述中國的情況。 3.We must serve the people whole-heartedly as comrade Lei Feng did. 我們要象雷鋒同志一樣全心全意為人民服務(wù)。 三、表示時(shí)間，意即"當(dāng)……時(shí)候"，"一邊……一邊""隨著……"。 1.As time went on ,Einstein'theory proved to be correct. 隨著時(shí)間的的推移，愛因斯坦的理論證明是正確的。 2.I read the book as I went along. 我邊走邊讀。 3.As a young man,he was a storekeeper and postmaster. 年輕時(shí)，他當(dāng)過店主和郵電局局長。 四、表示原因，意即"因?yàn)椋慈?。 As he wasn't ready in time,we went without him. 因他未能及時(shí)準(zhǔn)備好，我們就去了，沒有等他。 五、表示讓步，這種從句有兩個(gè)特點(diǎn)：１）語氣比though（although）引 起的從句強(qiáng)些。２）表語一般放 在本從句之首；如有可數(shù)名詞單數(shù)，前面也不 要冠詞。 child as he is ,he can tell black from white. 盡管他是個(gè)孩子，但他能夠分辨黑白。 Badly wounded as he was,he remained quite optimitic. 雖然他傷勢嚴(yán)重，但他仍然十分樂觀。 這種句型偶爾也表示原因。 He has made no progress at all ,lazy (fellow)as he,is. 因?yàn)樗麘卸�，所以毫無進(jìn)步。 六、引導(dǎo)表語從句： Things are not always as they appear. 事情不一定總是它們表現(xiàn)出來的那樣。 七、引導(dǎo)定語從句。 １）as引導(dǎo)非限制性定語從句，常指主句所表達(dá)的整個(gè)事情，可置句首、 句中、句末，常見 as we all k now,as Isee it 照我看來，as it appearsto us 依我看來。 As we have seen,oceans cover more than 70 of the earth. 正如我們所知道的，海洋占地球面積７０％以上。 ２）as引導(dǎo)限制性定語從句 From every corner of the island little people came to see the "Ma nMountain~as they called Gulliver. 小人們從海島的各個(gè)角落來看他們叫做'人山'的格利佛。 ３）as與 such,the same 連用，此時(shí)先行詞是一個(gè)具體的名詞，as在從句 中可作主語、賓語或表語。 The book is written in such easy English as beginners can understand. 這本書是用初學(xué)者也能讀懂的淺易英文寫的。 She studies in the same department as I do. 他和我在同一個(gè)系統(tǒng)學(xué)習(xí)。 八、as還可以與其他詞構(gòu)成成語型的連詞。 So(As)long as one inch of this deck remains above water,there is hope. 只要這船的甲板還有一英寸保持在水面上，就還有希望。 She has no experience in teaching as far as I know. 據(jù)我所知，她毫無教學(xué)經(jīng)驗(yàn)。 此外so as to＋不定式表示結(jié)果、目的，意即"以至于"，"以便"。 He raised his voice so as to be heard 他提高嗓門，好讓別人聽到。 又as to可以引起各種從句。 Y 活躍的ａｓou must remember to inform me as to whether we should do it. 這事究竟做不做，你要記得通知我。
